Joshua Haberman	10265aa56b	Directory restructure. Includes are now via upb/foo.h. Files specific to the protobuf format are now in upb/pb (the core library is concerned with message definitions, handlers, and byte streams, but knows nothing about any particular serializationf format).	14 years ago
Josh Haberman	8ef6873e0e	upb_stream: all callbacks registered ahead-of-time. This is a significant change to the upb_stream protocol, and should hopefully be the last significant change. All callbacks are now registered ahead-of-time instead of having delegated callbacks registered at runtime, which makes it much easier to aggressively optimize ahead-of-time (like with a JIT). Other impacts of this change: - You no longer need to have loaded descriptor.proto as a upb_def to load other descriptors! This means the special-case code we used for bootstrapping is no longer necessary, and we no longer need to link the descriptor for descriptor.proto into upb. - A client can now register any upb_value as what will be delivered to their value callback, not just a upb_fielddef*. This should allow for other clients to get more bang out of the streaming decoder. This change unfortunately causes a bit of a performance regression -- I think largely due to highly suboptimal code that GCC generates when structs are returned by value. See: http://blog.reverberate.org/2011/03/19/when-a-compilers-slow-code-actually-bites-you/ On the other hand, once we have a JIT this should no longer matter.

Joshua Haberman	61e5d367ff	Change the API for getting the bootstrapped defs. The symtab that contains them is now hidden, and you can look them up by name but there is no access to the symtab itself, so there is no risk of mutating it (by extending it, adding other defs to it, etc).	14 years ago
Joshua Haberman	5137ac8d61	Update to latest descriptor.proto.	14 years ago
Joshua Haberman	4dce5ab709	Fix upbc and descriptorgen, and update descriptor.	14 years ago
Joshua Haberman	ddb74551f4	Cleanup Makefile and mv descriptor/ -> src/	14 years ago
Joshua Haberman	229fcf7119	upb_def compiles again, though with lots of #if 0.	15 years ago
Joshua Haberman	63daaaca4f	Added constants for field names and numbers. Not used in this branch, but it is used in the src-refactoring branch.	15 years ago
Joshua Haberman	9e3f5e343b	Make upb_msgdef own all its data. This is in anticipation of making upb_msgdef's easy to dup. This involved removing all traces of any descriptors from the defs.	15 years ago
Joshua Haberman	040f7e6ba2	Significant memory-management refactoring any Python extension.	15 years ago
